Question 1

What is Non-Destructive Testing (NDT)?

Accepted Answer

Non-Destructive Testing (NDT) is a group of analysis techniques used to evaluate the properties of materials, components, or assemblies without causing damage. NDT methods are essential for quality control, safety inspections, and maintenance in industries like oil & gas, aerospace, power generation, and manufacturing.

Question 2

What are the main types of NDT methods?

Accepted Answer

The main NDT methods include Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Eddy Current Testing (ET), and Visual Testing (VT). Each method has specific applications depending on the material type, defect orientation, and accessibility.

Question 3

Why is NDT important for industrial safety?

Accepted Answer

NDT is critical for detecting defects before they lead to equipment failure, environmental damage, or safety incidents. Regular NDT inspections ensure structural integrity, extend asset life, reduce downtime, and comply with regulatory requirements in industries like oil & gas, nuclear, and aerospace.

Question 4

How do I choose the right NDT method for my application?

Accepted Answer

The choice depends on several factors: material type (ferrous vs non-ferrous), defect type (surface vs subsurface), accessibility, and required sensitivity. For surface cracks on ferromagnetic materials, use MT. For subsurface defects, UT or RT is preferred. PT works on non-porous materials for surface defects. Our consultants can help you select the optimal method.

Question 5

What NDT certifications does Atlantis offer?

Accepted Answer

Atlantis NDT offers training and certification for ASNT (American Society for Nondestructive Testing) Level I, II, and III across all major NDT methods including UT, RT, MT, PT, ET, and VT. We also provide preparation for CSWIP and PCN certifications.

Question 6

What is the difference between NDT Level I, II, and III?

Accepted Answer

Level I technicians perform specific calibrations and tests under supervision. Level II technicians can set up equipment, interpret results, and prepare reports. Level III professionals can design test procedures, train others, and interpret codes and specifications. Each level requires more experience and knowledge.

Question 7

How long does NDT training take?

Accepted Answer

Training duration varies by method and level. Level I typically requires 40 hours of classroom training, Level II requires 40-80 hours depending on the method. Certification also requires documented experience hours and passing written and practical exams.

Question 8

Do you offer online NDT training?

Accepted Answer

Yes, we offer blended learning options combining online theoretical training with hands-on practical sessions. This allows flexibility for working professionals while ensuring practical competency through in-person labs.
